In this chapter James gave direction to his readers to encourage and enable them to live at peace with God, others, and themselves. It ties in closely to chapter 1 (cf. 4:6 and 1:5, 21; 4:8b and 1:6-8, 15, 21, 27; 4:9-10 and 1:21).
"James 4 continues the same topic of strife, and addresses now not only the teachers of 3:14 but also the rest of the brotherhood who are in similar sin: strife springs from within (vv. 1-3) and is fostered by worldliness; love of the world and love of God cannot coexist (vv. 4-6); Christians must resist the devil and draw near to God (vv. 7-10)."151
Having dealt with the source of interpersonal and inner personal conflicts that believers in particular and all people generally experience, James dealt next with a different aspect of the same problem. He did so to motivate his readers further to forsake the philosophy of the world that puts self first. Criticizing others is dangerous not only because it is a form of selfishness but also because the critic exalts himself even over God when he criticizes.
4:11 The speaking in view is speaking disparagingly of, or down on, another Christian. To criticize another one must conclude that he is right and the person he is criticizing is wrong. This is passing judgment. The law in view probably refers to God's law generally in view of the context. We sin against God's law when we criticize a brother because God has revealed we should not speak against, or pass judgment on, our Christian brethren (cf. Lev. 19:15-18). We should submit to one another (e.g., Gal. 5:13; Eph. 5:21; Phil. 2:3). Rather than taking a position of humility such a person exalts himself to the role of judge (cf. v. 10).
"We must be careful to note the far-reaching consequences of James' teaching here: respect for law and order is necessary (as we are often told) for the health of modern society, but James goes on to remind us (v. 12) that, since God is the source of all law, what is ultimately at stake in a permissive society' is respect for the authority of God himself."169
4:12 James was speaking of judging other people without divine authorization to do so. Obviously God has delegated the responsibility of judging some civil acts to human governments, some church conduct to elders, and the behavior of children to their parents.
Judging our equals is a common sport, but it is inappropriate for mere mortals. We all are responsible to God ultimately and must leave the judgment of His servants up to Him (Rom. 14:1-13). We need to remember that we are on the same level with those we may wish to judge. We are brothers and neighbors (cf. Deut. 32:39; 1 Sam. 2:6-7; 2 Kings 5:7).
As in the previous chapters, James began with the exposition of a practical problem and moved on to its larger contextual problem, that is, its context in life. He already identified the source of interpersonal and inner personal conflicts as self-centeredness and explained that criticism places the critic in a seat that only God should occupy. Now he pictured a self-centered person living his or her life. He did this to enable his readers to see the root of this problem clearly.
